Only need 2 wires for the jack itself, the others will be jumpered using pushconnectors to the next outlet.. just cant remember which. Going by the pic, Id say orange needs to be on 2 9still sleeved and been in a krone punch) and the other 2 were likely in a push connector too (stripped) or twisted cheapo style

Looking at the picture, and, it is not normal, my suggestion would be to just put the red one on number 2, plug the phone in to it and see if you have a dial tone. The damage to the insulation on that wire makes it look like it has been punched down.

I take it that you did not strip the other 2 wires and they were like that? It looks like there is some oxidation on the bare wires so I think that they have been like that for a while, but, it could just be the photo. You don't strip the wires when you punch them down, but, who knows what has been done here in the past.

If that works, and you have other phones that don't, try holding the blue / green against 1 & 4 and see if the other phone gets a dial tone. Unfortunately, your phone wiring is a non standard mess and it is difficult to work out what is happening there.

It looks to me like the typical old 4-wire cable (red, white, blue, green) with the white gel-cap extended onto a white/blue wire. This typically uses the red and white wires which should be punched down onto terminals 2 and 5 on the BT jack

absolutly correct - the blue and green wires are not used (i dont know why they have been stripped back)

The white one has been extended to connect it to 2 - the red one goes on 5 - but please use the right tool to connect it - either the cheap 'The Warehouse' version that just push inserts the wires on or the correct Krone (or Cloned version) which inserts and cuts the wire off
